Hi, Looking at the PV seal sets which I have all appear to be the 4 'O' rings and 3 seals. No one appears to list the orange "o" rings that go round the end bush holders? Assume these are not the same as the 4nr black 93210-30734 type... cant see them listed or for sale.
Is it these are not replaced...
or anyone know where I can get hold of the 2 'o' ring seals ?
Thanks

Sorry I bet you wondered what I have been talking about. After speaking today with my local Yam shop it became apparent that my PV has an extra seal! I have 3 'O'ring seals per PV.. two as below in the middle and one at the end.. has anyone seen this or is it they have two groves and someone has put the seals in both.. is it ok like this as I am thinking good sealing option So tried the MB thinker retaining plates in the end groove and not sure if they should bottom out or just the tips go into the groove (as they appears slightly machined thinner towards the inner radius) I can see slight daylight in the middle of the radius.... the extg YAM plates fit snug and completely into the retaining groove.. had a look around looks like I have some odd aftermarket bushes here? And looking at the retaining groove it does look thinner to others I can see?  PV by Bozzy Bozzy, on Flickr |

The double o ring isn't standard
Usually only 1 oring and the retainer groove
2nd groove isn't usually there

I would suspect that been done to overcome a worn powervalve tunnel?
If you replace with standard, they may be wobbly and you’ll have to get the cylinders repaired?

Probably quite a good idea, I like someone’s thinking 👍

I know NK sells them but they must be a common seal ?

I found them online once and bought a bag of 30 but sadly now ran out, need to source some more
Orange food grade silicone I believe

Cheers thought they were different wants the thought around the retaining plates? Does that grove look thinner that standard?

I've always had to file down the thicker retainers on new bushes
